What data we process
When you buy a book, the payment is processed by Stripe on its own secure page: Stripe sees your card, we never do. From the purchase we receive your email, your country and the book you bought, so we can deliver the file and help with any problem.
If you join the club, we keep your email, your name if you give it, the status of your membership, your reading progress, your votes and the topics you ask for, so the club can work. To sign in we email you a code, and a session cookie is stored on your device.
If you leave a review, we keep the rating, the text and, if you write it, your name. It is only published if you check that we may do so.
To know how many people visit the page and at which step they leave the checkout, we count visits anonymously: the type of step, the day, the approximate country and the page you came from. We do not use tracking cookies or store your IP address.
Emails
We email you the book, the sign-in codes and the club notices. Emails with recommendations are only sent if you accept them or where the law allows it, and every email has an unsubscribe link.
Who we share it with
Only with the providers needed to run the store: Stripe (payments), Cloudflare (hosting of the page and the files) and Resend (sending emails). We do not sell or hand over data.
Your rights
You can ask to see, correct or delete your data by writing to grandpawrench@practicguides.com.
